The torque capacity of a two pads disk brake

The torque capacity of a two pads disk brake

The torque capacity of a two pads disk brake can be expressed as

T = μ F r (1)

where

T = torque (Nm)

μ = coeficient of friction

F = force on pad (N)

r = mean radius of pad (m)

Required pad pressure can be expressed as

p = F / A (2)

where

p = pressure (Pa)

A = pad area
